How a Calamity Necromancer Retires

(Author’s note: The content that magic does not flow to the amputated part in episode 104 has been deleted, and only the content that the leg is necrotic remains. Sorry for the confusion.)

I came to the Seron Research Center in Korea with Nakamura and told Nakamura.

“Let’s start by tidying up. You want legs that won’t interfere with combat, right?”

“you’re right.”

“Is that leg really hopeless?”

“It continues to rot faster.”

It means that the necrosis is progressing rapidly.

“How does it look?”

At my words, Nakamura said with a determined expression.

“You just need to be able to fight.”

It doesn’t matter how you look, so you want legs with good performance.

To be honest, making a bridge with good performance is not very difficult.

Since he declared that he would not make it with a human being, he made a skeleton leg in a shape similar to the existing leg as much as possible, then pulled out another corpse’s morale and shoved it in like crazy.

The problem is how to move that leg.

“To fight, you need to be able to move your legs naturally… Haa, how do you implement this?”

In a complex combat environment, even Nakamura, who has the ability to accelerate instantly, must be able to move his legs freely.

“Hmm.”

While thinking about it for a while, Baek Sang-ho pulled the cart and came inside.

“Chairman, I brought them all.”

Baek Sang-ho brought prosthetic legs sold in the market.

Since I had no knowledge about prosthetic limbs, I was instructed to get them for reference.

“First of all, Mr. Nakamura, I made a reservation at a famous hospital in Seoul, so please try again. do you know Will I be able to save my leg?”

A prosthetic leg is the next best thing, and the best thing is to save the leg.

At my words, Nakamura said with an expression that he did not expect much.

“Will it be cured?”

“I’m going to try it, and if it doesn’t work, I can’t help it. Anyway, I need time to study, so pretend to be fooled and go see a doctor.”

In the end, Nakamura nodded with a disapproving expression.

“All right.”

“The car is parked outside, so you can just get in.”

When Nakamura went outside, I took out the prosthetic legs Baek Sang-ho had brought and said,

“Now, shall we do prosthetic research in earnest?”

*

I bought all types of prosthetic legs, from low-end prosthetic legs sold in the market to high-end prosthetic legs tailored to each person, and analyzed the operation principle.

Inexpensive prosthetic legs placed the center of gravity at the bottom of the leg and were only at the level of automatically sagging when the leg was lifted, but high-end prosthetic legs costing tens of millions of won were operated by robot AI.

“It is a method that automatically recognizes the motion of the floor and the wearer through AI and sensors and moves accordingly.”

“Then what if you do something radical other than usual? For example, suddenly turning around.”

“Anyway, prosthetic limbs are prosthetic limbs, so up to that level of function…”

A robotic prosthetic leg using AI and sensors.

It’s not bad, but the limits are clear.

At most, it helps to make walking look natural.

“Is there anything like that? A prosthetic arm or leg that operates by reading brain waves or nerves.”

“There is, but it is still in the testing phase.”

“Why?”

“I don’t know the details, but they say they can read brain waves, but there is too much noise, so it’s difficult to accurately interpret them.”

“hmm.”

I thought about it for a while and said.

“Is there anything better?”

“Yes, this is about the things that have been commercialized once.”

The level of the prosthetic leg is worse than expected.

“This is a headache.”

I tried to make a prosthetic leg in combination with a robot, but at this level, it is not helpful at all.

“After all, reading people’s will is the problem.”

A prosthetic limb that reads a person’s will and operates according to that will.

Then an idea comes to mind.

‘mana? Shall we use magic?’

As long as you can read your will, what does it matter if the mediator is brainwaves or nerves?

‘If I carve a magic circle into a prosthetic limb and make it move in the same way as the magic moves… wouldn’t this work?’

The most realistic alternative for Nakamura, who is SS-class and can handle mana freely.

this would be possible

But I feel sorry.

“It would be nice if ordinary people could use it, too.”

If only magic power is used as a means of controlling prosthetic limbs, it will become a prosthetic limb that can only be used by SS class members.

If you’re going to do it, you should make it available to anyone.

How nice it is to show fantasy with Seron Land and break down the difficulties of reality with Skeleton.

Although you won’t be able to make a lot of money with this, you will definitely be able to take care of one image.

“Hmm.”

But no matter how much I think about it, I can’t come up with a suitable method.

“Let’s just bump into each other.”

I said looking at Baek Sang-ho.

“We are going to test prosthetic legs for people with leg pain, so please recruit some volunteers.”

*

Prosthetic leg testers were recruited, and when the prosthetic leg was supported with a considerable reward and the condition that the test was successful, test applicants poured in like a wave.

I started research in earnest with the recruited applicants.

First of all, the first test was a prosthetic leg that reversed the skeleton’s driving algorithm.

The human body does not move individually, but the whole body moves in harmony.

If the normal leg moves by applying the skeleton’s driving algorithm using this, the prosthetic leg moves on its own with an algorithm optimized for that movement.

Just like that, a man puts on a skeleton that covers both legs like an exoskeleton and takes a step forward with his normal leg.

Then, the movement of the normal leg is detected and the prosthetic leg is also moved according to the corresponding algorithm.

“Oh oh!”

The man smiled brightly and said.

“This is the best! There is little difference in walking!”

The words of a very satisfied man.

But I wasn’t at all.

“…this won’t work.”

It moves according to the algorithm according to the movement of the opposite leg, and there is no problem when the same movement is repeated.

However, if you do a special action, such as suddenly stopping or turning your body, the continuity is broken and an unnatural posture emerges.

It doesn’t fall thanks to the balancing algorithm, but it’s well below what I expected.

Of course, this is enough to satisfy a man who has only used prosthetic legs that were on the market.

“Uh ha ha. You can climb the stairs so easily?”

I looked at him and said with a sad expression.

“There is a possibility for ordinary people, but there is no option for combat use.”

I said looking at Baek Sang-ho.

“Proceed to the second test.”

The second prosthetic leg was a kind of deformable unmanned skeleton that directly controls the prosthetic leg according to the contact surface and strength of the upper and lower teeth by creating a magic circle on the teeth.

The man wearing the second prosthetic leg presses the activation button and then controls the leg by rubbing his teeth up and down and side to side.

Then the man’s legs moved slowly, but in the end he fell down without even taking a single step.

It can’t be easy when you try to control things with your teeth that you used to control naturally like breathing.

But the man was satisfied this time too.

“Ooh! oh my god. A prosthetic leg that can be manipulated however you like!”

What kind of world have you lived in that makes you so happy with things like that?

I said looking at the man.

“Are you okay?”

“It’s okay! I’ve been living without my left leg for nearly 10 years, but this is the first prosthetic leg!”

The man said with a hopeful face.

“With these prosthetic legs… I think I’ll be able to live a little more comfortably.”

“is it so?”

To be honest, this one is also a failure by my standards.

If you become proficient in manipulating with your teeth, you will be able to walk much more naturally, but moving your legs by manipulating each movement will require considerable mental energy consumption.

‘Have I been too greedy?’

For the general public, the prosthetic leg made now is overwhelmingly more upward compatible than the prosthetic leg already commercialized.

So, I think the most realistic thing is to make a prosthetic leg that moves with magical power and give it to Nakamura, regardless of whether you are satisfied with this much for ordinary people and can only use SS grade.

‘Let’s do a little more. If I try a little more and it doesn’t work, I just go with the original plan.’

That time when I was about to put it down half way and proceed with the experiment.

“Ugh!”

The man who smiled brightly after taking the test suddenly trembled and said.

“Left, the left heel is big!”

uh?

The prosthetic leg is removed and the left leg is empty, but the man struggles with his hand toward that left leg.

“My heel hurts!”

what is this sound.

From nob le mtl dot com

My whole left leg is missing below the knee, but my heel hurts?

An embarrassing situation where the missing part hurts.

I urgently told the medical staff who came to help with the test.

“Why are you here? Does your missing left heel hurt?”

Then the medical staff said with a bitter expression.

“It’s a phantom pain.”

“Phantom pain? What is it?”

“To put it simply, the brain makes an illusion.”

The medic looked at the man’s chart and said.

“All nerves lead to the brain and the brain makes decisions. However, when it was amputated, the nerve transmission in the missing part was cut off, and it became a defective nerve. Then the brain misrepresents those defective nerves as pain or itching.”

“Is there any treatment?”

“There is no cure. I just have to live with the expectation that it will be alleviated. But this person… has been experiencing phantom pain for 10 years already. ah. Fortunately, mitigation methods are charted. Bring a mirror!”

At that, another medic brought a mirror and pointed at the man’s right leg.

“Come on, Mr. Sangwook. This leg is Sang-wook’s left leg.”

“Hoo-wook. Hoo-wook.”

“Try moving your toes slowly.”

Then, as if familiar, the man slowly moved his right toe.

“Your left toe moves.”

What is that doing?

You call the left leg while shining the right leg?

“This time on the left knee…”

The man who moved his right leg while looking in the mirror smiled and said.

“It has improved a lot. thank you sir.”

“no.”

The medical staff who came back after taking such an emergency measure.

“Didn’t you just show me your right leg in the mirror?”

“you’re right. It’s called mirror therapy. It’s a kind of self-suggestion that conveys visual information to the brain that the left leg is fine. It may seem ridiculous, but it is one of the many treatments that people actually see the results of.”

The man himself knows it well.

That leg is the right leg, not the left leg.

But just passing it on to the brain as visual information can ease the pain.

“her.”

By the way, you’ve been suffering like that for 10 years?

If you feel pain and itching in an area where you don’t have it, you can’t do anything about it.

At best, optical illusions with mirrors are the only treatment methods.

I didn’t know that I had never seen such injured people in Seron because they were often abandoned right behind.

“Whoa.”

Originally, I was going to try and dry it a little more, but I’ll have to try harder.

“Okay, then the next test… Huh?”

But wait a minute.

The brain is weak in visible visual information, enough to alleviate symptoms just by giving an optical illusion.

Did you say phantom pain?

It must be a phantom pain because it is a pain in a place where there is no place.

I said with my eyes shining.

“What if I go beyond mirrors and use real illusion magic?”

Illusionary magic that disrupts the optic nerve and shows the scene I want to show.

If the magic shows that a real leg has been created, wouldn’t it be possible to deceive not only the brain but also the patient himself?

“Ohh?”

Then, of course, the brain recognizes the leg shown as a fantasy and tries to move it, right?

I said to Baek Sang-ho, who was waiting next to me.

“Didn’t they say that brain waves are difficult because they have a lot of noise?”

“That’s right.”

“Who did you hear from?”

“I consulted with a university research team that studies brain waves.”

“is it so?”

Wouldn’t it be possible to amplify the brain waves as if painless torture is possible by activating pain to the extreme?

“Are you sure of your skills?”

“I heard that it is the best in Korea.”

“Then please contact me again. There is something I want to ask you.”

*

The brain engineering professor greets me with a bright smile.

“Welcome, Chairman Han.”

“Nice to meet you, Professor Wu.”

“He said he was interested in our research.”

I nodded and said.

“Yes, that’s right.”

“hahahaha. That’s really good news. Our research team is currently conducting research on manipulating various objects using brain waves, and significant progress has been made…”

As soon as he meets me, the professor who starts with his research achievements.

It’s a look I’ve seen often.

Securing research funds is the first task of professors.

I listened to the professor for a while and nodded my head moderately, and when the professor finished speaking, I started asking questions in earnest.

“So, when will a prosthetic arm using brain waves be commercially available?”

“…a prosthetic arm.”

“yes.”

“Shall I be honest with you?”

“Please speak.”

“We are still far away.”

The professor said with a calm expression.

“Current brain wave research has reached the level of controlling drones and robots using brain waves.”

oh?

So, isn’t that a lot of progress?

“However, that is only at the level of reading very, very simple brain waves, such as moving back and forth. EEG is a radio wave in which various information from neurons in the brain is mixed. Of course, brainwaves continue to change even in the brief moment of conversation like this. There are even differences in the characteristics of brain waves for each individual, so it is virtually impossible to perfectly catch only the neural response of a part of the body precisely with only the waves.”

Hmm.

“In the end, the surest way is to have a person do a repetitive motion and find a specific brain wave that comes out each time the action is taken.

for a moment.

Are you saying that you can’t interpret the brain waves because you can’t use the part of the body that already has the problem?

Then, wouldn’t it be enough to trick the brain and the patient as if it were possible to use body parts with illusion magic?

“Besides, have you seen it? People sitting on an EEG analyzer on TV. They put EEG monitors all over the head and measure brain waves, to measure brain waves as deep as possible. However, in the end, since the brain waves are measured from the scalp to the inside of the head, the accuracy is inevitably low. Even if you do this, the accuracy is poor, but it needs to be further reduced to commercialize the prosthetic limb.”

That’s it, if you amplify your brain waves, that’s it.

The professor seems to tell you to give up, but the more you listen, the more possibilities you see.

I said with a smile.

“What if, what if there was a way to solve all of that?”

“What do you mean by that?”

“The problem now is that we have to do repetitive actions, so we need to find a specific brain wave that comes out each time, but there is no part to do repetitive actions, right? Each person’s brain waves are slightly different, so it’s meaningless just analyzing other people’s brain waves.”

“you’re right.”

“Then, wouldn’t it be okay to make temporary body parts for people without legs or arms, let them move, and then amplify their brain waves and measure them?”

Then the professor said with a puzzled expression.

“Aside from brainwave amplification, you say you make temporary body parts? even move? If that’s possible, why make a prosthetic limb?”

“There is something like that.”

Then the professor suddenly takes out his leg from under the desk and rolls up his pants.

Then, what appeared was a prosthetic leg.

“If there is such a thing, I will be the first to run and try it.”

The professor himself was the one who needed the prosthetic limb the most.

it was better

It’s my job, so I’ll be more passionate about it.

I looked at the professor and said.

“If you answer my question, I will make it clear what I am talking about. Is it possible to make a temporary body part and compare and analyze the brain waves generated by moving them and the usual brain waves?”

“At least it will be overwhelmingly more likely than it is now.”

“okay.”

I got up from my seat and approached the professor.

“Take off that prosthetic leg for a while. Please roll up the pants on the other side as well.”

Then, the professor takes off his prosthetic leg with a dubious expression.

‘Can I make the right leg look the other way around?’

I slowly covered the professor’s eyes with my hand and said.

“Okay, let’s attach a temporary bridge from now on.”

And I, who cast illusion magic by creating a magic circle.

“I’m going to let go now. Then you will see the left leg. But don’t move. Did you know?”

“What the hell is that…”

“Just feel it. Come on?”

When I let go of my hand, the professor said with a puzzled expression.

“I didn’t feel anything, but what do you mean you feel?”

“Look at your left leg.”

And the moment the professor turns his eyes to his left leg.

“uh······?”

said the professor in amazement.

“My, my left leg!”

When the professor, who saw the left leg embodied with illusion magic, was horrified and tried to stand up, I stopped the professor and said,

“Come on, calm down. If I move, I may not be able to use this leg again.”

At my bluff, the professor shuts his mouth and stays still.

“From now on, on the count of three, I will raise my left thumb. One, two, three.”

At the same time as counting three, Illusion magic makes it appear as if the left thumb is lifted.

Then the professor said with a face full of tears.

“Ooh, move. I just moved my toe!”

After all, the professor mistakenly thinks he moved.

“Okay, that’s it.”

When I snapped my fingers, the professor’s legs disappeared like a mirage.

The professor touched his leg with a puzzled expression and said.

“What, what? my legs! Where did my leg go?”

“I just showed you the bridge as an illusion, which is my ability. That is, it is not real. But is it real?”

The professor came to his senses at the words, but still said with a bewildered expression.

“You said it was an illusion? Did your thumb really move?”

“I made it look like it was moving.”

I went back to my chair and sat down.

“Wouldn’t it be possible to create illusions by creating illusions as if they were actually moving in this way, then measuring the brain waves coming out of them and comparing and analyzing them with the original brain waves? And non-majors came here because they were curious. How are you, Professor?”

I said with a grin.

“Is this a possibility?”
